Re: SIGPIPEs

[Maurice Bremond]

>or tell us that you are already using it.
All our clients and servers are running cfengine 2.1.14

in cfservd.conf I use :

   AllowMultipleConnectionsFrom = ( "$(some_net)" )

So I can run several cfagent at the same time on a client of some_net :

# cfagent & cfagent & cfagent

without getting SIGPIPE from a client.

Without AllowMultipleConnectionsFrom we have the SIGPIPEs from the
other cfagents running concurrently.

In this case, the message is something like 

cfengine:xxxx: Authentication dialogue with xxx.xxx.xxx.xxx failed
cfengine:xxxx: Unable to establish connection with xxx.xxx.xxx.xxx (failover)
cfengine:xxxx: Received signal 13 (SIGPIPE) while doing [no_active_lock]
cfengine:xxxx: Logical start time Thu Apr 28 15:35:56 2005
cfengine:xxxx: This sub-task started really at Thu Apr 28 15:35:58 2005


But anyway, even with AllowMultipleConnectionsFrom we are getting
SIGPIPEs randomly.

We have have about 150 clients, a SplayTime of 15 minutes, a
MaxConnections of 150, and few sigpipes each day.

Some examples Ex
